Description

  The present invention relates to a slider for a slide fastener, and particularly relates to a slider for a slide fastener that greatly improves the assembling property between a handle holder and a slider body and has high production efficiency.

  Conventionally, as a structure for attaching the handle holder to the slider body, a structure using a round wire pin is used, but it is necessary to provide shaft holes in the handle holder and the slider body. In view of this, a slide fastener slider has been devised in which productivity is improved without using a round wire pin when attaching the handle holder to the slider body.

  For example, in the slide fastener slider described in Patent Document 1, after the flange provided on the handle holder is fitted into the slide groove of the slider body, the caulking build-up portion provided on the slider body is placed on the upper surface side. The flange of the handle holder is crimped and fixed to the upper wing plate of the slider body by crushing with a punch or the like, thereby simplifying the operation of attaching the handle holder to the slider body. In the slide fastener slider described in Patent Document 2, a part of the side wall portion of the handle holder is pressed toward the concave portion of the slider body, and the raised portion formed on the upper blade is used as a flange of the handle holder. The mounting strength between the handle holder and the slider body is improved by pressing toward the fixing concave portion provided and crimping and fixing the handle holder to the slider body at two locations.

  Next, assembly of the slide fastener slider 10 of the present embodiment will be described with reference to FIGS.

  First, the opening / closing member 50 and the coil spring 11 are assembled to the slider body 20. Specifically, after the coil spring 11 is mounted in the spring mounting groove 33 formed on the upper blade 21 of the slider body 20, the guide portion 51 of the opening / closing member 50 is fitted into the opening / closing member guide groove 32 of the upper blade 21. And insert. Further, in a state where the opening / closing member 50 is pushed in and the coil spring 11 is contracted, the projecting piece portions 34 provided on both sides of the opening / closing member guide groove 32 are pushed and bent toward the center in the width direction of the slider body 20. Accordingly, the opening / closing member 50 and the coil spring 11 are prevented from falling off the upper blade 21 of the slider body 20. The opening / closing member 50 is attached to the slider body 20 so as to be slidable along the opening / closing member guide groove 32 while being always urged rearward by the elastic force of the coil spring 11.

  Next, the leaf spring 12, the stop claw body 60, the pivot pin 13, and the handle holder 40 are assembled in this order on the slider body 20 to which the opening / closing member 50 and the coil spring 11 are assembled. Specifically, as shown in FIG. 4A, the leaf spring 12 formed in a rectangular shape by a spring steel plate is inserted into the spring chamber 35 provided between the left and right wall portions 27a and 27b of the claw support portion 27. Then, the stop claw body 60 is inserted between the left and right wall portions 27a and 27b from above while engaging the lower concave portion 67 of the stop claw body 60 and the positioning convex portion 36. Further, the pivot pin 13 is fitted into the U-shaped groove 27 c of the nail body support portion 27 and placed on the pivot recess 66 of the stop nail body 60.

  When assembling the pull handle holder 40 described later, the leaf spring 12 and the pivot pin 13 are swaged and fixed to the claw support portion 27 so that these parts do not come off even if the pull handle holder 40 contacts. It is desirable to keep it.

  Subsequently, as shown in FIG. 4B, the flange 41 of the handle holder 40 is inserted into the sliding groove 29 from the front end of the slider body 20, and further, as shown in FIG. 5B, the handle holder. 40 is slid along the sliding groove 29 toward the rear of the slider body 20.

  At this time, the upper surface 41a of the flange 41 is inclined such that the thickness t of the flange 41 gradually decreases from the rear end portion 41c of the flange 41 toward the front end portion 41d, while the groove height L of the sliding groove portion 29 is increased. Are uniformly formed in the front-rear direction. For this reason, the front-end part 41d of the up-down direction clearance between the flange 41 and the sliding groove part 29 is larger than the rear-end part 41c of the flange 41. Thereby, the handle holding body 40 can be inclined to the state where the front end portion 41d is lifted upward (see FIG. 5B), and when the handle holding body 40 slides toward the rear of the slider body 20, Interference between the convex portion 42 and the wall 37 of the slider body 20 is prevented.

  Further, since the rear end wall 42b of the convex portion 42 is inclined with respect to the lower surface 43a of the fixed-side base end portion 43, as shown in FIG. While being guided by the wall 37 of the body 20, the body gradually tilts counterclockwise and is slid toward the rear of the slider body 20. And the convex part 42 gets over the wall 37 of the slider body 20, and engages with the concave part 30 (refer Fig.6 (a)).

  Next, as shown in FIG. 7, the upper surface portion 21 b of the upper blade 21 located above the sliding groove portion 29 of the slider body 20 is crushed by a punch or the like toward the flange 41, thereby The flange 41 is caulked and fixed to the upper blade 21. Thereby, the pull holding body 40 is engaged with the convex portion 42 and the concave portion 30, and the flange 41 is crimped by the upper blade plate 21, so that both the engagement and the crimping are combined to hold the pull handle. The body 40 is firmly fixed to the slider body 20.

  Further, both side surfaces 41b of the flange 41 are inclined in the front-rear direction (see FIG. 3A), and the width W of the flange 41 gradually increases toward the front end side of the slider body 20, so The contact area is increased and the caulking strength is improved. Further, since the front end wall 42a of the convex portion 42 is formed substantially perpendicular to the lower surface 43a, the engagement with the concave portion 30 is reliably maintained against the forward force acting on the handle holder 40. .

  Further, as shown in FIGS. 6B and 7B, the stepped portion 46 of the handle holding body 40 abuts on the pivot pin 13 and is fitted to the U-shaped groove 27c of the nail support 27. The attachment strength of the pivot pin 13 is improved by pressing the support pin 13 from above. Accordingly, the stop claw body 60 is supported so as to be swingable about the pivot pin 13. Further, since the front end side of the stop claw body 60 is biased upward by the elastic force of the leaf spring 12, the stop claw body 60 rotates counterclockwise in FIG. 6B. The nail | claw part 64 protrudes from the nail | claw hole 31 to the element guide path 24, and engages with the fastener element not shown.

  As shown in FIG. 7, the opening / closing member 50 is urged rearward by the coil spring 11, so that the gap between the rear end portion 44 of the handle holding body 40 and the upper blade 21 of the slider body 20 is between The formed gap 14 is closed by a proximal end side closing portion 52 of the opening / closing member 50, and the gap formed between the continuous edge portion 49 of the handle holder 40 and the upper blade 21 is also an opening / closing member. It is closed by 50 front end side closing portions 53.

  In order to attach the handle 70 to the slide fastener slider 10 assembled in this way, the attachment shaft portion 73 of the handle 70 is pushed toward the gap 14 from the rear end side of the slide fastener slider 10. Thus, the opening / closing member 50 is slid forward along the opening / closing member guide groove 32 of the upper blade 21 against the urging force of the coil spring 11, and the attachment shaft portion of the handle 70 is opened via the opened gap 14. It is assembled by inserting 73.

  As described above, according to the slide fastener slider 10 of the present embodiment, the handle holder 40 extends from the left and right side surfaces of the fixed base end portion 43 in the width direction and extends in the longitudinal direction. The slider body 20 is formed at the front end of the upper blade 21 and is engaged with the protrusion 42 and a sliding groove 29 that accommodates the flange 41. A convex portion 42 by inserting the flange 41 into the sliding groove 29 and caulking the upper surface portion 21 b of the upper blade 21 positioned above the sliding groove 29 toward the flange 41. Is engaged with the recess 30 to fix the handle holding body 40 to the slider body 20, so that the attachment of the handle holding body 40 and the slider body 20 is facilitated, and the productivity is improved. Further, since the flange 41 is inserted into the sliding groove 29 and the upper surface portion 21b of the upper blade 21 is caulked toward the flange 41, the vertical direction between the handle holder 40 and the slider body 20 is fixed by caulking, The front-rear direction of the handle holder 40 and the slider body 20 is fixed by the engagement between the convex portion 42 and the concave portion 30. Further, since the entire flange 41 is caulked, the attachment strength can be increased, and the caulking trace does not remain on the handle holder 40, and the appearance is improved.

  Further, since the upper surface 41a of the flange 41 is an inclined surface in which the thickness t of the flange 41 gradually decreases from the rear end portion 41c of the flange 41 toward the front end portion 41d, the flange 41 of the handle holder 40 is connected to the slider body 20. When inserting into the sliding groove 29, the handle 42 can be tilted so that the convex 42 can be smoothly engaged with the concave 30. Further, when an external force is applied to the handle holder 40, the thickness t of the rear end portion 41c of the flange 41 where the force tends to concentrate can be increased, and the strength is improved.

  Further, since the side surface 41b of the flange 41 is inclined so that the width W of the flange 41 gradually increases from the rear end portion 41c of the flange 41 toward the front end portion 41d, the upper surface portion 21b of the upper blade 21 becomes the flange 41. When caulking in the direction, the contact area between the caulking portion of the slider body 20 and the flange 41 is widened, and the mounting strength is improved. In addition, the flange 41 of the handle holder 40 can be easily inserted into the sliding groove 29 of the slider body 20.

  Further, the convex portion 42 is formed to protrude toward the slider body 20 on the lower surface of the fixed-side base end portion 43 of the handle holder 40, and the concave portion 30 is formed on the front end portion side of the upper blade 21. By engaging the portion 42 with the recess 30, the front-rear direction of the handle holder 40 and the slider body 20 is fixed, and the attachment strength can be improved.

  In addition, this invention is not limited to what was illustrated to the said embodiment, In the range which does not deviate from the summary of this invention, it can change suitably.

  For example, in the above embodiment, the flange 41 has the upper surface 41a inclined so that the thickness t gradually decreases from the rear end portion 41c toward the front end portion 41d, but the present invention is not limited to this.

  For example, as shown in FIG. 8, in the slide fastener slider of the first modified example, the flange 41 has a uniform thickness t from the rear end portion 41c to the front end portion 41d. On the other hand, the sliding groove portion 29 of the slider body 20 has a groove height L slightly smaller than the total dimension of the thickness t of the flange 41 and the protruding height of the convex portion 42 of the handle holder 40 as in the first embodiment.
